Parker received a
recess appointment from
President Calvin Coolidge on October 3, 1925, to a seat on the
United States Court of Appeals for the Fourth Circuit vacated by Judge
Charles Albert Woods. "[W]hen seventeen states and the Congress of the United States have for more than three-quarters of a century required segregation of the races in the public schools, and when this has received the approval of the leading appellate courts of the country including the unanimous approval of the Supreme Court of the United States at a time when that court included Chief Justice Taft and Justices Stone, Holmes and Brandeis, it is a late day to say that such segregation is violative of fundamental constitutional rights," Parker wrote in his 1951 opinion. The case went to the Supreme Court and, in 1954, a unanimous Court ruled in
Brown that “in the field of public education, the doctrine of ‘separate but equal’ has no place” and “separate educational facilities are inherently unequal". The following term, the Court held additional arguments to determine how the
Brown decision would be implemented. In a case that became known as
Brown II, the Court decided that, rather than order immediate desegregation in public schools throughout the country and risk civil unrest and resistance, it would let local authorities come up with plans to implement the
Brown decision “with all deliberate speed.” As a result, the
Briggs case went back to the Fourth Circuit, and Parker issued an opinion in 1955 that
Brown only outlawed state-sponsored segregation of public schools. “The Constitution, in other words, does not require integration. It merely forbids discrimination. It does not forbid such segregation as occurs as the result of voluntary action. It merely forbids the use of governmental power to enforce segregation,” he wrote. In other words, de facto public school desegregation was okay, but
de jure segregation was not while J. Harvie Wilkinson, III, concurred, calling Parker the person who "most influenced school desegregation" in the post-
Brown era. The Supreme Court would unofficially overturn the Parker Doctrine in 1968, ruling in
Green v. County School Board of New Kent County, 391 U.S. 430 (1968), that school boards had an “affirmative duty” to end segregation “root and branch,” and emphasizing that “the time for mere ‘deliberate speed’ has run out.” ==Unsuccessful Supreme Court nomination==
